@chasinghosts :
So you're saying no snorkel needed even though your butt is under water?
Never said butt was under water...
Think it through, doesn't work either.
OK, I went and got a "visual" from the net so maybe this will help:

Now, if she could breath through that badonkadonk and therefore didn't need the snorkel, she could dive her head down closer to the underwater scenery and get a better view....
